Question

Two teams played a football match.Thehome team won the match by 2 goals to 1.How many different possible half time scores were there?
​

Answer 1

Answer:

In sports (particularly association football), a two-legged tie is a contest between two teams which comprises two matches or "legs", with each team as the home team in one leg. The winning team is usually determined by aggregate score, the sum of the scores of the two legs. For example, if the scores of the two legs are:

First leg: Team A 4–1 Team B

Second leg: Team B 2–1 Team A

Then the aggregate score will be Team A 5–3 Team B, meaning team A wins the tie. In some competitions, a tie is considered to be drawn if each team wins one leg, regardless of the aggregate score. Two-legged ties can be used in knockout cup competitions and playoffs.

In North America, the equivalent term is home-and-home series or, if decided by aggregate, two-game total-goals series.
